I've updated the website to be more resilient against user mistakes such accidentally adding white-space characters to your address. Could you check if you see your stats now?

@Jason: Thanks for reporting. In reality the password is currently not used at all. Need to update the page.

Most of the time whattomine is a bit over-optimistic but even then your earnings are pretty close to what the site predicts and I've even added 10 MH.

According to the logs you did:

[2017-12-14 20:49:11.4494] [I] Adding 0.03378 MONA to balance of MGgR33XDmW1XLmBMihbGrDBqvxSsFwoHmY

@Tone: First, sorry to see you go. Second, and this in no way meant sarcastic - could you post your 24h earnings on your new pool given a roughly similar number of blocks found?

That' neither weird, nor something sinister nor a bug. I was contacted by a miner and he proved that he got a bit shafted by that block mess yesterday with his shares getting pushed out the window. I've sent him some compensation and that big amount you see there going to the address you've listed went back to the pool's change address. This transaction is also listed as latest payment on the Monacoin Pool's Payments list and includes the compensation I've mentioned and the left over balance of the miner.

When funds get transferred using Bitcoin technology or anything that its derived from Bitcoin, the daemon attempts to sent it from unspent inputs. If it cant find an unspent input that covers the amount to send, it sends the smallest one it has and requests the change to be returned to a new address. In this case the input was an entire block reward.

There's not a single share under that address in the database. I'm going to grab an old copy of minerd to test it using your config.

I will look into this.

Investigating.

Fixed. I've setup monitoring alerts for any such anomalies and noticed the problem when I woke up. But thanks for reporting.
